<p><P>PROBLEM TO BE SOLVED: To provide a golf ball 2 having excellent flying performance, scoffing resistance and control performance. <P>SOLUTION: The golf ball is provided with a core, a cover and many dimples 12 formed on the surface of the cover. The cover mainly consists of polyurethane elastomer. The shore D hardness of the cover is≥30 and≤55. The occupancy Y of the total area of the dimples 12 to the surface area of a virtual ball is≥75%. The number NL of the dimples 12 whose diameters are≥3.90 mm is≥75%. The ratio of the number ML of the dimples 12 whose diameters are≥3.90 mm, whose (Re/Rw) is≥0.5 and≤1.5, and whose Re is 2.0 mm≥and≤5.0 mm to the number NL is≥50%. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
